By way of explanation, it may be stated that mining machines produce dust which, being carried back by the air from the drill, finds lodgment in the lungs of the miner, t0

5 the undermining of his health. The foregoing being understood, it may be stated that one of the objects of this invention is to take care of the dust produced from a mining machine ofthe drill type. Another object of the l invention is to provide novel means for adjusting the drill with respect to the work. l

It is within the province of the disclosure to improve generally and to enhance the utility of, devices of .that kind to which the l present invention appertains.

IVith the above and other objects in view, which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of 0 construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed, within the scope of what is claimed, without departing '25 from the spirit ofthe invention.

,In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention, mounted iu working position in a mine, the

-I 3Q collecting bag for the dust being omitted;

' Figure 2 is a top plan;

Figure 3 is an enlarged section of the collecting head; t

Figure 4 is a cross-section on the line 4.-4 of Figure 3;

Figure 5 is a front elevation; Figure 6 is a cross-section on the line 6-6 of Figure 3; Figure 7 is an elevation showing a modification; and

Figure 8 is a top plan of the modification disclosed in Figure 7.

Referring particularly to the form shown in Figures 1-6 of the drawings, there is provided a support 1, including side bars 2 connected by a rear cross piece 3 and a front cross piece 4. Sockets 5 are connected to the side bars 2 .near to the forward ends thereof. In the sockets 5, legs 6 are mounted for vertical adjustment. Any suitable means may be supplied for adjusting the legs 6 vertically. In the present embodiment of the invention. but not of necessity, cross pins 7 are mounted in the holes 8 of the legs 6, the cross pins engaging beneath the sockets 5. 55 The numeral 9v designates a prop which passes pivotally through the rear cross piece 3. The prop 9 has any desired number of longitudinally-spaced openings 10, in any one of which may be placed a pin 11, the pin 60 11 engaging beneath the cross piece 3 to holdl the prop 9 in place. At its upper end, the prop 9 has longitudinally-adjustable extension 12 which is slidably mounted in the prop. Any suitable means may be provided for holding the extension 12 in place. In the present embodiment of the invention, but not of necessity, there are holes 16 in the prop 9. and through any one vof these holes 16,'and through the extension 12, a pin or other securing element 15 may be placed. The extension 12 has a cross piece 14 whereby the extension may be handled con-vv veniently. It will be seen that when the legs 75 6 are engaged with the Hoor of the mine, as shown in Figure 1, the lower end of the prop 9 being engaged with the floor of the mine,' and the extension 12 being engaged with the roof of the mine, the support 1 will be held f8@ in place securely.

The numeral 17 marks a. cup-shaped 'collecting head, the base 18 of which is secured to the side bars 2 of the support 1. Inthe forward end of the head 17 there is a chan- 85 nel 19 in which fits a resilient sleeve 20, madeof rubber ora rubber compound.' As shown at 21, the sleeve 20 flares and tapers as it extends forwardly, thereby to enhance the resiliency of the sleeve; Securing elements 9 mounted in charged through the ethe 22 are mounted in the head sleeve in place in the hea The numeral 23 designates a roller, journaled for rotation on a bracket 24 carried by the lower part 25 of a clamp, the upper part of the clamp being designated by the numeral 26. As shown in Figure 4 of the drawings, the parts 25 and 26of the clamp are connected together by a pivot element 27, and this pivot element 27 serves also to hold the parts 25 and 26- of the clamp on the rear end of the collecting head 17. The parts 25 and 26 of the clamp are held together by any suitablec means, such as a bolt and wing nut 28. Y

In the cooperating parts 25 and 26 of the clamp, are located the members of a resilient gasket 29.

In its bottom part, the collecting head 17 has an outlet 34 which is 'extended laterally, as shown in Figure 5. The numeral 35 designates a porous collecting receptacle or sack which is clamped at 36, removably, on the end of the outlet 34.

e numeral 37 designates a pipe connected Y t e pneumatic mechanism 31 whereby the drill is operated. The pipe 37 communiv cates with a flared bore or mouth 39 in the top of the collecting head 17. Baifles 38 are .the rear end of the collecting head andproject forwardly into the collecting head The ballles38 converge downwardly toward the outlet 34, asshown in Figure 6 lof the drawings.

About the pulley is trained a exible element 41. One end of the flexible element 41 is anchored as shown 'at 4`2 on t e forward end of the platform 33. The flexible `element 41 is extended rearwardly underneath the platform 33 andl is wound about `a shaft 43 which is supported for lrotation in the side bars. 2 ofthe sup-port 1. The numeral 44 designates a shaft which' is also supported for rotation in the side bars 2.' A flexible element 45 is 44, the iiexible element 45 being 46 on the platform 33. The sh f are operatively connected by 1 gears 47.

drill. or tool 30 carries dust backwardly into the collecting head the gasket 29 as a 33, the platform 33 being wound about the shaft be a. ts 43 and 44 f lecting head provide 17, the dust being forced through the outlet 34 into the bag 35, .where the dust is collected, the air passing-on through the bag, because the bag is porous. In this way, the dust is not blown back into the face ofthe miner, to be inhaled with disastrous consequences'which are well known to those skilled in the art.

It is desirable to prevent the dust from escaping at the place where the tool 30 reciprocates in the butt of the collecting head 17. It is for this purpose that the gasket 29 is used. Some persons prefer to dispense with the asket 29 and the clamps 25 and 26, and to re y upon the blast of air through the pipe 37, the blast of air forcing the dust downwardly, between the baffles 38, into the outlet 34, the blast through the pipe 37 carrying away the dust which otherwise might find its way out throughthe rear end of the head 17, about the drill 33. Some operatives will prefer to take olf the pipe 37 and to rely upon means for preventing dust l from finding its way backwardly out of the head 17 about the drill 30.

By means ofthe crank 48, rotation may be imparted toffthe shaft 43,y the intermeshin gears 47 rotating the shaft 44. The flexible elements'41 and 45 are operated to shift the platform v33 back and forth. and in this way, the drill 30, with the mechanism 31 which operates it, may be adjusted with respect to the breast of the mine.

In the modification shown in Figures 7 and 8, parts hereinbefore described have been designated by Vnumerals previously used, with the suix a. The modification consists in making the frame 1a longitudinally adjusta ble. The front members 50 of the frameor support 1a are tubular, the rear members 49 of the frame being telescoped for sliding adjustment into vthe front members 50. Set screws 51 are threaded into the front members and, engaging with the members 49, hold the support or frame at any length to which it may have been adjusted. The rear members 49 are connected at their rear ends by a tie 52, in the form of a bolt, on which the prop 53 is mounted, the prop 53 corresponding to the prop 9 and having openings 54 for the reception of the tie or bolt 52.

he machine forming the subject matter of .this application is simple in construction, but

it affords an effective means whereby dust will prevented from being blown back from a post drill or other mining machine, into the ace of the minor, to be inhaled to the detri ment of his health.

at is claimed is:

mining machine comprising a dust-cold upon one side and near with a dust outlet, the head upon its opposite side with a u1 -pressure conduit discharging into the head .and toward the outlet, a drill mountedA to reciprocate in the head, between the conduit 1'0 los lll

to 1ts rear end ing supplied and the outlet, and bales projecting forwardly with respect to the rear end of the head, the conduit being provided at its inner end with a ared mouth which permits the pressure-Huid to spread and pass around the drill, the balles being located on opposite sides of the drill and converging toward the outlet, to direct the ressure-uid into the outlet, as thepressureuid passes across the drill. In testimony that I claim the foregoing as `my own, I have hereto aixed my signature.
